宫内节育器综合临床评价指标的探讨

本文通过专家咨询（Ｄｅｌｐｈｉ）法，应用常用的宫内节育器单项临床效能指标（Ｉｎｄｉｃａｔｏｒ，Ｉ）研制了一个ＩＵＤ综合临床效能指标（ＣｏｍｐｒｅｈｅｎｓｉｖｅＰｅｒｆｏｒｍａｎｃｅＩｎｄｉｃａｔｏｒ，ＣＰＩ），并对ＣＰＩ的意义、特点及其应用进行了探讨。ＣＰＩ的特点、是全面地反映了ＩＵＤ的临床效能，计算简便。应用ＣＰＩ值可直接全面比较各种ＩＵＤｓ的临床效能，避免了既往那种应用不同的单项效能指标比较会得出不同结论的矛盾。应用本文研制的方法计算的ＣＰＩ值，其范围在２４０～３８０之间，一个综合临床效能较好的ＩＵＤ其ＣＰＩ值应大于３２０。参考有关文献，应用ＣＰＩ试行评价了六种常见ＩＵＤｓ：金属单环、ＴＣｕ２２０℃、宫形铜环、Ｎｏｖａ－Ｔ、ＴＣｕ３８０、ＬＮＧ－ＩＵＤ，结果表明综合临床效能最佳的是宫形铜环、ＴＣｕ２２０Ｃ。本文在国内、外首次探讨了ＩＵＤ综合评价指标，此项研究尚有待于进一步探讨。

Development of a Comprehensive Intrauterine Contraceptive Devices Performance Indicator

A comprehensive intrauterine contraceptive devices performance indicator (CPI) is developed based on a well-designed questionaire survey of 48 experts around the world. The significance,charac.teristics and application of CPI are also discussed. The characteristics of CPI is that it reflects the performance of IUDs from six aspects:continuation rate,pregnancy rate,expulsion rate,rate of termination due to complications,rate of serious complications,rate of moderate/light complications. The performance of different IUDs can be compared directly by CPI,which is comprehensive,avoids the previous conflict of using different single indicators leading to different conclusions. By using the method developed in this paper,the range of CPI is normally between 240～380,CPI more than 320 indicates good performance. The authors attempt to use CPI to evaluate six common IUDs: Steelnees ring, TCu220C, Uterine Cavity-shaped (Cu ) IUD, Nova-T,TCu380Ag, LNG-IUD. The results highly recommend the Uterine Cavity-shaped (Cu) IUDand TCu220C.
